I keep noticing that the SQRT code I wrote recently for a POSIX shell keeps appearing, (the green colour sticks out like a sore thumb).
So I decided to take a look on Google.
Guess what?
UNIX.COM comes first in Google's listing just from two words, see image...

Hi I just stumbled on to these forums today, and I relatively new to unix. I am trying to figure out how to find the square root of a number using a shell script. I am using bash and I have searched and searched but cannot figure out square roots. Hopefully someone can point me in the right... (3 Replies)

cbrt
SQRT(3) BSD Library Functions Manual SQRT(3)NAME
cbrt, cbrtf, cbrtl, sqrt, sqrtf, sqrtl -- cube root and square root functions
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
#include <math.h>
double
cbrt(double x);
float
cbrtf(float x);
long double
cbrtl(long double x);
double
sqrt(double x);
float
sqrtf(float x);
long double
sqrtl(long double x);
DESCRIPTION
The cbrt(), cbrtf(), and cbrtl() functions compute the cube root of x.
The sqrt(), sqrtf(), and sqrtl() functions compute the non-negative square root of x.
RETURN VALUES
The cbrt(), cbrtf(), and cbrtl() functions return the requested cube root. The sqrt(), sqrtf(), and sqrtl() functions return the requested
square root unless an error occurs. An attempt to take the sqrt() of negative x raises an invalid exception and causes an NaN to be returned
(except that the square root of -0 is valid and equal to -0.)
SEE ALSO fenv(3), math(3)STANDARDS
The cbrt(), cbrtf(), cbrtl(), sqrt(), sqrtf(), and sqrtl() functions conform to ISO/IEC 9899:1999 (``ISO C99'').
HISTORY
The cbrt() function appeared in 4.3BSD. The sqrtl() function appeared in FreeBSD 8.0. The cbrtl() function appeared in FreeBSD 9.0.
